XTOOLAD20 Pro OBD2 Scanner for Car 2025 Wireless Code Reader for iPhone & Android, All System Diagnostic Tool for Check Engine, ABS, SRS, Oil Reset, Voltage, Performance Test, No Subscription Fee

This review is for the Xtool AD20 Pro, a compact, wireless, dongle-style OBD2 scanner that transforms your smartphone into a full-featured diagnostic tool. At around $55, this is an exceptional entry-level scanner that punches well above its weight class in terms of features and functionality.I own several Xtool products, including the A30M (a more advanced wireless scanner priced around $160 with no subscription required) and the D7S, a professional-grade wired scanner that does require an annual subscription. The AD20 Pro sits at the entry point of their lineup, but don’t let that fool you, this tool delivers surprisingly advanced diagnostics for its price.The AD20 Pro supports a wide range of vehicles. I have successfully used it on a 2014 Jeep and a 2011 Suburban. When connected to a new vehicle, the app will prompt you to download the specific diagnostics for that make and model, simple and efficient.Once connected, it performs an All-System Scan, reading and clearing fault codes across systems including Engine, Powertrain, SRS, ABS, TPMS, and more. It easily handles diagnostics that most cheaper tools miss. Additionally, it includes valuable features like Oil Light Reset and Battery Check, which are frequently used maintenance functions.A good convenience is its built-in DTC Lookup, which pulls up definitions online for any fault codes, helpful for understanding and addressing issues quickly. Other features include: Live data streaming, Freeze frame data,ECU info, O2 sensor, component testing, engine load, RPM, fuel trims, MAF, misfire counters, voltage, and more.What you will not get at this level are the bi-directional controls and advanced reporting features (like saving and printing diagnostic histories), which are available on models like the A30M and D7S. But that is a fair trade-off considering the ease of use and price point.Bottom line: The Xtool AD20 Pro is a very good value for beginners or DIYers who want more than just basic code reading. It is a great starting point with plenty of features typically found only in more expensive models. Highly recommended for anyone looking for a reliable, feature-rich OBD2 scanner at an entry-level price.

I recently put the Advancer A20 Pro to the test, and it stands out not only for its impressive features, lifetime free updates, and ease of use but also for its exceptional customer service, making it an even more commendable choice for vehicle diagnostics.I used the A20 Pro on a several cars, including a 2009 Dodge Ram 1500, 2008 Mazda CX9, 2010 Honda Civic, 2011 Hyundai Sonata, 2003 Toyota Matrix, and a 2001 BMW 530i. This allowed me to assess its performance across various makes and models.Diagnostic Insights: The A20 Pro effectively scanned the cars with and without check engine lights, providing valuable insights into each vehicle's health. Some of the codes that the A20 Pro was able to find were:• Emission Codes: I was able to identified common emission codes on the Toyota Matrix, shedding light on potential issues with the emission control systems.• ABS and SRS Codes: Pinpointed an ABS code on the Mazda. On the Honda it pulled up several SRS codes related to the seatbelt restraint system.• TPMS Codes: The Mazda had some TPMS codes, offering detailed information about the tire pressure monitoring system.• Despite no check engine light, my 2009 Dodge Ram 1500 revealed codes related to the recirculation/ventilation door on the A/C system. This discovery explained the issue with heat not coming out of the lower vents, demonstrating the A20 Pro's capability to identify non-obvious problems.Pros:• Bluetooth Connectivity: The A20 Pro's Bluetooth capability is a game-changer. Being cordless enhances the overall user experience, allowing for greater flexibility and ease of movement during the diagnostic process.• Exceptional Customer Service: XTool customer service second to none. I also have the D8 and had many questions when I first received it. I have consistently experienced prompt responses to emails, and what sets them apart is the proactive approach — I've even received follow-up emails just to check if I resolved my issue. This level of customer care is truly commendable.• Ease of Use: The A20 Pro stands out for its user-friendly design, making vehicle diagnostics straightforward even for those less experienced in automotive technology.• Great Value: Considering its price point, the A20 Pro provides impressive value, delivering great performance without breaking the bank.• Live Data Analysis: A standout feature is the A20 Pro's ability to provide live data, enabling real-time diagnosis of potential issues. This feature allows users to address problems promptly, enhancing the overall utility of the device.• Continuous Monitoring: Another notable advantage is the ability to keep the A20 Pro plugged in, allowing for continuous monitoring of live data as soon as you start your car and while you drive. This real-time feedback enhances the user's ability to detect and address issues on the go. I’ve kept mine plugged into my truck for a couple of weeks now and as soon as pull up the Advancer app it shows the live data.• Free Lifetime Updates: No costly updates each year. The A20 Pro has free lifetime updates.Cons:• Switching Between Vehicles: One minor drawback is the initial challenge in switching between vehicles. However, after using it for a while, I found it to be a minor inconvenience. Hopefully they will streamline the process with future updates.If you are in the market for a scanner and want to get some valuable information for a DIY repair or just want to get a leg up on the mechanic before you take to them for repairs…I would not hesitate to go with the A20 Pro.
